Genomic and phenotypic screening of the A. E. Watkins landrace wheat collection identifies beneficial novel haplotypes demonstrated to improve modern wheat without negative linkage drag or pleiotropy.

The PIN-FORMED (PIN) auxin efflux carriers in the plasma membrane are activated by the D6 serine/threonine protein kinase (D6PK). A recent study reveals how D6PK is anchored to membranes and trafficked between the plasma membrane and transport vesicles.

Plants constantly adjust their gene expression and metabolism to thrive in diverse environments. In legume root nodules, the surprising role of zinc as an intracellular messenger links environmental changes to transcriptional control.

This Review aims to define an updated nomenclature for plasma membrane domains in plants. The authors are experts in this field who unite here in an effort to eliminate the ambiguities and confusion that have persisted until now.

The pyrenoid contains internal membrane structures that are required for efficient carbon fixation. The two proteins SAGA1 and MITH1 are necessary for the biogenesis of these membranes and the delivery of bicarbonate to the pyrenoid matrix.

Two algal proteins, MITH1 and SAGA1, play key roles in formation of membranes that deliver CO₂ to the pyrenoid, a CO₂-concentrating organelle. Their discovery marks a key milestone towards engineering a pyrenoid into land plants for improved yields.

High-severity wildfires in the Alaskan Arctic tundra promote shrub growth, which drives a fire–greening positive feedback loop. The existence of this feedback loop suggests that wildfires have an important role in the changing tundra landscape amid rapid Arctic warming.

This study generates and phases the complete genome assembly of a model plant Nicotiana benthamiana, revealing insights into the structure, epigenetic landscape and evolutionary dynamics of its centromeres following allotetraploidization.

The efficient induction of embryos without fertilization, which is important for crop breeding and hybrid seed production, can be achieved by combined expression in the egg of BBM1 and WOX9A, two rice transcription factors normally expressed from the male genome.

Hybrid seed failure in plant breeding arises from disrupted endosperm development. Reduced maternal sirenRNAs and increased expression of AGL transcription factors cause abnormal gene regulation in the endosperm, preventing successful wide species crosses.

Arctic warming has led to widespread greening across the tundra. Utilizing remote-sensing and field data, this study identifies a positive fire–greening feedback loop operating across regional scales and highlights the emerging issue of wildfires in one of Earth’s largest carbon sinks.

Analysis of the FLUXNET2015 dataset provides observational evidence for widespread thermal acclimation of canopy-scale photosynthesis and its timescales across diverse biomes, improving its representation in land surface models.
